The Use of ETS Activity to Estimate In Situ Respiration Rates of Benthic Infauna

该奖项支持与毕格罗海洋科学实验室的J. Christensen博士合作的一个为期一年的项目，该项目将尝试对选定的底栖动物进行呼吸速率测量。底栖生物呼吸速率的测量对于我们了解陆架和近岸水域的有机碳消耗至关重要。然而，生物速率是最难进行的环境测量，研究人员将应用一种灵敏的生化测定方法来测量呼吸，即电子传递系统（ETS）活性。将用实验室耗氧量测量来校准碳排放交易体系的测量，并将调查一系列环境条件下的呼吸作用。实地研究将在缅因州南部的近岸水域进行。

This award supports a one year project with Dr. J. Christensen of Bigelow Laboratory for Ocean Sciences that will attempt to make respiration rate measurements of selected benthic infauna. The measurement of benthic respiration rates is critical to our understanding of the consumption of organic carbon in shelf and near shore waters. However, biological rates are some of the most difficult environmental measurements to make, and the investigators will apply a sensitive biochemical assay for respiration, the measurement of electron transport system (ETS) activity. The ETS measurements will be calibrated with laboratory oxygen consumption measurements and respiration under a range of environmental conditions will be investigated. The field study will be done in the near shore waters of southern Maine.
